Cogswell 1949 Journal 62 Big Lagoon, Humboldt Co., Calif. Aug. 15 Caught the following mammals in trap line set, last night in V- traverse which crossed Pitcher Creek at two points, with traps # 1-6 & 47-53 being near the grassy old logging road & all others well within the Rubus spectabilis & R. parviflorus thickets. Peromyscus maniculatus - 3 ad. ♂, 5 ad. ♀, 2 juv. ♂ (some in traps in open areas, fewer (only?) at deepest part of thicket traversed) Sorex trowbridgii - 1 Sorex pacificus - 2 Zapus trinotatus - 1 see species accounts. on the return to camp thru the thickets of the pasture I took an immature Spinus tristis (7492 miller) from flock of 150+ which were in the thickets & flew up to alders. About 2:30 p.m. Murray & I drove to the ranch with abandoned house, old barn, & 10 acres or so of grassy slope which is situated at the end of a dirt road contouring along the w. slope of the first ridge east of the lagoon (see map) at 550' altitude. En route we passed thru extensive brushy mountainside which I will describe later. At the ranch I set out 20 traps for small mammals, baited with walnut and oatmeal. The grass is so thin that I mostly placed them in the edge of bushes which are here mostly Asteris agiulina, Rosa sp., Rhododendron ♂, or dentale Rhus vitifoliae, and Faultheria shallon. Toured this brushland & grass for birds for 45 min. I will list tomorrow.
